Tubes or SS that's what your really looking at, also 48w-90w but both are fine with either.
I'd think the Accuphase will be better made and hold its resale value longer. No tubes to replace when they go, as they will. More features in the E280 as well. Meters!.
I just don't think Prima Luna is at the same level as Accuphase. But if you want tubes its an option, there are better options out there for similar money though IMO of course.
I took me a long time to sell my friends prima Luna preamp and mono blocks when he passed a couple years ago. Resale value is not high for them in my experience.
